How do I fix a defect in the freestyle render if there are no apparent causes?
To fix this problem in Blender, I added my claw, which was the cause of this issue, into a separate collection by pressing M in the viewport and selecting New Collection. After this, I renamed the layer where all my objects were then, I created two additional layers. Then, I went to each layer and hid the object that I didn't want in that layer  by right-clicking that collection and going to Layer and clicking disable from View Layer. I went to each layer's properties and checked Use for Rendering under View Layer. I added a new freestyle line set for the two new layers and clicked on the box that said collection, then I marked the collection that I wanted to have the freestyle lines on, which was the object visible in that layer. Afterward, I went to the composite tab, added an additional render layer, and plugged both layers into an Alpha Difference node. I hit render and turned the images into a sprite sheet in another software. Here is evidence that the problem was fixed:

BTW this is in Blender 2.92, so to create a new layer, you must go to the very top of the window, and right next to the Scene selection buttons, there is a set of layer management buttons. All you have to do is press the button that looks like two papers stacked on each other to make a new layer.
